In matrix composing and line casting .ma-

chines, especially those having a mould wheel adapted to carry a plurality of moulds s mul taneously, it is already known for removable ejector. blades to be provided so that when changing over from one measure orbody to another, the ejector blade may also be quickly changed. For this purpose it has already been proposed to arrange edgewise one above the other aplurality of narrow' ejector blades, each having the width of a typographical unit or a multiple thereof, and to connect with the ejector driving mechanism, a number of these blades which in width will collectively correspond'with the length of the respective lines'or slugs. It has also been proposed to store in a receptacle a plurality of juxtaposed ejector blades, those corresponding to the desired width being brought into operative position v through lateral displacement.

Both the aforesaid constructional forms have the disadvantage that'the ejector blades can only be so selected that the thinnest will correspond to the slug of smallest body dimension which will be used, usually six point, and that also the width of the-ejector blades can only approximate to the actual length of the slugs. As the thickest slugs are also ejected by these thin ejector blades considerable trouble arises through their becoming embedded into the feet of the slugs and the latter sticking in the moulds instead of being ejected.

The present invention overcomes this difiiculty by the fact that the machine is equipped with a removable ejector blade magazine which contains a number of ejector blades corresponding with the moulds present on the mould wheel. The ejector blades themselves are also removable from the magazine. It is thus possible to store in this magazine, such blades as actually correspond with the moulds for the time-being on the mould wheel, i. e. ejectors which will accurately fit each of the respective moulds and which may easily be substituted one for another. If the mould itself is altered or the moulds exchanged for others. the e'ector blade ma azine 1s si-' multaneously taken put and a corresponding alteration of the respective ejector blades is effected.

The drawingsillustrate byway of example a constructional ,form' of the present inventive idea and in these drawings Figure 1 is a diagrammatic illustration of the ejectingmechanism of a'matrix'cornposing and line casting machine;

Figure 2 is a horizontal section through Figureli' r I Figure 3 1s an elevation of the toplpa'rt of Figure 1 as seen from the left-hand side;

section on the line magazine. containing the" different ejectorblades 5 (in the present constructional form four of these'blades are providedto correspond with a mould wheel having four moulds). The magazine a can be moved laterally inamanner similar to that adopted 1n existing constructional forms, i. eforward and backward relatively to the'plane of representation in Figure 1, so as to bring any requlsite e ector blade I) lnto the operative position in which it will be coupled with the ejector 0. This ejector 0 consists o-f'a blade similar to the blades b. The coupling may be conveniently effected through a T- shaped recess 6 in the ejector blade 5-, and

a. T-shaped projection or head 0 on the ejector 0 (see Figure 9.). The ejector blades 1) are inserted into the magazine a from the front. In order to provide guides for'the blades Z) in the magazine a, the top wall of said magazine (Figures 7 and 8) is provided near the front with recesses within which filling strips or. plates'e are capable of being turned about a common pivot In their operative position, the filling plates engage above and below with recesses (Z; they may, however, be rocked upwardly about the pivot 6 into the position shown in dotted lines in Figure 7. As the individual ejector blades Z), as shownparticularly in Figure 10, are thicker at their rear ends, and, at those parts are of the same thickness the ejector 0, they can only be inserted into the magazine after the filling plates 6 have been raised into the dotted-line position shown in Figure 7. After the insertion of the ejector blades whose rear extremities completely fill the width of the magazine, the filling blades 0 are turned down between or beside the respective ejector blades, as is shown in Figure 10, in respect of two of such blades. each filling plate 6 together with the body size of the respective blade Z) is uniform, and equals the corresponding dimension of the rear end of the ejector blade. Consequently,

' if a change of ejector from one body size to another is made, it is also necessary to change the respective filling plate or plates 0,,which can easily be effected after removing the pivot pin 6 For all practical purposes it is sul'licient to have two different thicknesses of ejector blades, viz :-thin ones forthe smaller bodies and thicker ones for the larger bodies. When ejector blades-wider than the ejector c are required they are provided, as: shown in Figure 9, with upstanding projections b at the front. The whole magazine with the ejector blades is inserted into the so-called mould wheel slide 7 in the manner shown in Figures 1, 2, 5 and 6. The mould wheel slide, as is already known, is that portion of thermachine which carries the pivot f about which revolves the mould wheel f carrying the moulds f I11 order to, insert the magazine a into the mould wheel slide 7", the latter is provided with guides f adapted to receive a corresponding number of projections on the mag azine, and, in addition to this, the magazine itself is provided with. a handle 9 for facilitating its removal andreplacement. The mould wheel slide 7 is slightly cut away in front at the top in order to permit the removal of a. magazine containing ejector blades 5 having the before-described projections 6 When it is desired to effect a change of ejector blade magazine, the socalled vise frame is lowered frontwise, so as to give access to the mould wheel slide j, which must then be pulled forward until its rear edge passes beyond the front of the machine frame when the said magazine is free to be removed from the machine.

The before-mentioned guides f are, as shown in Flgures 2 and 6, obhquely inclined The body size of,

so that longitudinal displacement of the magazine will simultaneously cause the latter to be moved laterally. This lateral movement serves to bring the ejector blades 6 stored in the magazine successively into and out of engagement with the ejector c.

F or the purpose of moving the magazine longitudinally, the latter is provided with a projecting stud ]t adapted to be engaged by the forked rear extremity of a link 7:

whose other end is attached to one armof a hand lever i. The forked end of the link permits of easy disconnectioi'i from the stud it, by lifting said link into a position such as that shown in dotted lines in Figure" 5, when such disconnection is required as a preliminary to effecting a change of magazine. In order to retain the link is in 013- erative engagement with the stud h, as shown, it is provided with a laterally extendingpin a, and the mould wheel slide f is provided with a cover plate or latch m to said slide, the said cover plate being adapted to overlie the pin. a and thereby prevent the link 70 from accidentally leaving its operative position although the pin a is free to travel. beneath the cover plate m in the longitudinal direction. Inorder to retain the cover plate m in the locking position, a spring-pressed pin m Figure 5, is provided, which engages with a corresponding recess in the underside of the said cover plate m. l H

The before mentioned hand lever 2' is bifuroated at its lower end, and is pivotally mounted in a block or bracket 0 by means of a pivot 2' The upper end of this lever which can be turned about a pivot m fast 7 is provided with a handle whilst the lower 7 end is pivotally connected with the link it ported by a guide or bracket; *2" provided on.

the front plate of the machine.

The ejector 0 is rigidlyattached to the so-called ejector slide 8, which is connected in theknown manner with the ejector lever t by means of a connecting rod u. The connection between the rod 10 and lover i is effected through a guide member '2) pivoted to the said lever, and in which the rod a is longitudinally slidable. A spring to connects the rod 10 with the guide member o and pulls the ejector slide 8 back until the rear end of the latter contacts with a stop a lever, whilst the return movement iseifectedthrough a roller 2 on the lever 6, being engaged by acam 2 The mode of operation of the device is as follows :-when a line has been cast in they usual manner, the mould Wheel f rotates until the mould slot is in front of the ejector, then, through the action of the connecting rod u, the ejector slide 8, and ejector c and the selected ejector bladeb all move forward together to eject the slug from the mould. hen a changeof mould is effected,-

the lever 2' must be correspondingly rocked to move the ejector blade magazine .a in a lateral direction, and thereby disconnect from theejector c, the blade last previously engaged with it, and engage with said ejector the particular blade appropriate to the newly selected mould.

When the moulds on the mould wheel are actually changed for others of different measure or body, the whole magazine a with the ejector blades 6 is removed and other blades of the appropriate dimensions are substituted for those last previously used, the filling plates 6 being also changed if rendered necessary by such substitution of ejector blades.

It is to be understood that the details of the present constructional form may be varied, as the essential feature of the present invention resides particularly in the fact that the ejector blades are stored in a special magazine which may be changed as a whole.
